Breath test for stomach and esophageal cancers shows promise

Posted by in categories: biotech/medical, electronics

For several years, Professor George Hanna from Imperial College London has been directing work toward the development of a test that can detect cancers of the esophagus and stomach by measuring the levels of five chemicals in a patient’s breath. These chemicals are butyric, pentanoic and hexanoic acids, butanal, and decanal, which previous research has identified as pointers to the presence of stomach or esophageal cancer.

In 2015, Professor Hanna announced the results of the first clinical study analyzing the breath samples of 210 patients. The patents exhaled into a breathalyzer-like device, which used a selected ion flow tube mass spectrometer to detect the presence of any of the five aforementioned chemicals in the breath sample. The 2015 study achieved a 90 percent accuracy rate in correctly identifying the two cancers, and a recently completed, broader study has also proven successful.

The new study collected samples from 335 people across four London hospitals. Around half of the group had been diagnosed with stomach or esophageal cancer and the other half had shown no evidence of cancer after having an endoscopy. After analyzing all the samples, the new breath test achieved an 85 percent accuracy rate, correctly identifying those both with and without cancer.

Pull A Body Apart With This Augmented Reality App

Posted by in categories: augmented reality, biotech/medical

Looking for that perfect gift for the medical student in your life? Search no more.


Is it wise to make medical students feel like renegade fictional genius Tony Stark, magically waving human bodies apart like the holographic diagrams in the Iron Man basement lab? Should we use technology to make millennials feel like superheroes? Stop asking difficult philosophical questions and look at how cool this is.

This augmented reality app is called Project Esper. It uses hand gestures to allow the users move and study anatomy. Users can pull the human body apart and investigate the organs and limbs piece by piece. Look—just look at this magical Star Trek karate:

Australian archaeological startup raises $679,000 to rebuild ancient sites in VR

Posted by in categories: education, virtual reality

Luv this.


Archaeology isn’t an easy job, but it becomes easier in virtual reality, if you can walk around ancient buildings as if they were still there.

Lithodomos VR, an Australian virtual reality archaeological startup, knows this and has raised $900,000 in Australian dollars ($679,000 in U.S. dollars) in a seed funding round.

Researchers design 3D system to detect circulating tumor cells

Posted by in category: biotech/medical

Someday, we will have glasses or contacts that will be able to detect tumors and notify us or even contact doctor’s office to set up the appointment for us.


Researchers have shown that they could efficiently capture and simultaneously filter out the circulating tumor cells (CTCs) permanently from cancer patients’ whole blood, which otherwise could gain access into the blood and invariably cause metastasis.

LSD alters perception via serotonin receptors

Posted by in categories: biotech/medical, media & arts, neuroscience

Interesting study on brain receptors.


Researchers from UZH have discovered how the perception of meaning changes in the brain under the influence of LSD. The serotonin 2A receptors are responsible for altered perception. This finding will help develop new courses of pharmacotherapy for psychiatric disorders such as depression, addictions or phobias.

Humans perceive everyday things and experiences differently and attach different meaning to pieces of music, for instance. In the case of psychiatric disorders, this perception is often altered. For patients suffering from addictions, for instance, drug stimuli are more meaningful than for people without an addiction. Or patients with phobias perceive the things or situations that scare them with exaggerated significance compared to healthy people. A heightened negative perception of the self is also characteristic of depressive patients. Just how this so-called personal relevance develops in the brain and which neuropharmacological mechanisms are behind it, however, have remained unclear.

Scientists Identify A Brain Hormone That Can Trigger Fat Burning

Posted by in categories: food, neuroscience

Scientists, have identified a brain hormone that can trigger fat burning in the gut.

Researchers from The Scripps Research Institute (TSRI) in the US found a brain hormone that specifically and selectively stimulates f at metabolism, without any effect on food intake.

The findings, published in the journal Nature Communications, in animal models could have implications for future pharmaceutical development.

TDP43 and Alzheimer’s Study

Posted by in categories: biotech/medical, life extension, neuroscience

TDP-43 Protien tied to Alzheimers according to a Mayo Clinic Study.


Since the time of Dr. Alois Alzheimer himself, two proteins (beta-amyloid (Aβ) and tau) have become tantamount to Alzheimer’s disease (AD). But a Mayo Clinic study challenges the perception that these are the only important proteins accounting for the clinical features of the devastating disease.

MIT’s Food Computers Set the Stage for Open Source Agriculture

Most of us probably don’t think too much about the foodstuffs we buy in the supermarket. But behind the scenes, today’s food production system relies on a centralized, industrial-scale supply chain that’s still dependent upon soil-based agriculture for the majority of our food crops.

In many instances, that means that food has to travel long distances from farm to table, meaning that food has lost much of its freshness and nutritional value by the time it reaches your table. There’s also a growing awareness that this model isn’t sustainable: the pressures of increasing urbanization and loss of arable land, rising populations and the increased frequency of extreme weather events like droughts and floods — brought on by climate change — means that slowly but surely, we are going to have to change the way we grow our food.

CAE Healthcare Unveils First Mixed Reality Ultrasound Simulation Solution

Posted by in categories: augmented reality, biotech/medical, computing, holograms

My doctor needs one of these.


CAE Healthcare announced the release of CAE VimedixAR, an ultrasound training simulator integrated with the Microsoft HoloLens, the world’s first self-contained holographic computer. The announcment marks CAE Healthcare as the first company to bring a commercial Microsoft HoloLens application to the medical simulation market.

VimedixAR delivers an unprecedented simulation-based training experience, allowing learners to interact and move freely within a clinical training environment that is augmented with holograms. For the first time, students will be able to examine 3D anatomy inside the body of the Vimedix manikin. As learners practice scanning an animated heart, lungs or abdomen, they will observe in real-time how the ultrasound beam cuts through anatomy to generate a ultrasound image.
